Sask. researcher says provincially-encouraged oil, gas extraction method could put groundwater at risk

A University of Saskatchewan researcher says a form of oil extraction being encouraged by the Saskatchewan government needs more research and monitoring to avoid potential long-term contamination of drinking water in the province.
Grant Ferguson said his research suggests "waterflooding," a conventional form of oil extraction, could become a bigger problem for Saskatchewan than the more controversial practice known as fracking.
